OPHTHALMIC MOUNTING.

Application filed August 16, 1922. Serial No. 582,152.

T all whom it may concern: members thereto, and it is also fOllIld in Be it known that I, IVAYNE S. SEARLES, a practice that when these end pieces are so citizen of the United States, residing at bent their natural tendency is to bend back Providence, in the county of Providence and or straighten out when in practical use and 5 State of Rhode Island, have invented cerso move out of their designed operativepo- 60 tain new and useful Improvements in Ophsiti'on, and to obviate this difficulty I have thalmic Mountings, of which the following swaged and upset the stock and thus formed is a specification. or molded these end pieces into such shape This invention relates to improvements in as to strengthen the same and also to remove ophthalmic mountings and method of formany straightening tendency, and the following the same, one of the objects of this ining is a detailed description of one construcvention being to provide a method of uption of end piece by which these desired resetting the stock of the end piece by a swagsults may be accomplished.

To this rearwardly extending portion of the end piece, I have "hinged the temples 12 by the hinge joint '17.

My improved frame is very strong, durable and practical 1n construction.

The foregoing description is directedisolely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting-to all the mechanical changes to which the invention is susceptible, the invention being defined and limited 01115 by the terms of the appended claims.

I claim:

2. An ophthalmic mountingcomprising a non-metallic framehaving end pieces of a lateral thlckness greater than that of the lens rim, and having a portion of the end piece extending forwardly of the plane :of the forward side edges of the lens frame,- to resist forward bending of the end ,piece.

3; An ophthalmic mountingcomprising a non-metallic frame having end pieces which extend .both forwardly .and rearwardly of the corresponding planes of the side edges of .the .lens rims, to resist bending of the end ;piece.

4;. An ophthalmic mounting comprising a g non-metallic frame having end pleces of a lateral thickness greater than that of the lens rims and arranged to extend both for- Wardly and rearwardly oit the correspondto resist bending, and a temple hinged :to

each of said end pieces.

6. An improved method of forming .a 111011- metallic ophthalmic mounting, which consists in cutting the frame from sheet stock with end pieces thereon, and shaping these endpieces Joya :swaging operation with a .rearwardly extending portion for hinging a temple to said vend piece.

7. .An improved method of forming anonmetallic ophthalmic mounting, which consistsin cutting the frame from sheet stock with end pieces thereon and swagin'g "the end pieces into a lateral [thickness ,greater than that of :the rims. v y

In testimony whereof-I afliX my signature.
